"No, I don't think he does," she told Good Morning America, on Monday morning.

She said the president "wants the truth to come out to the American people,” adding: “He is asking that it be done through the House Intelligence Committee, and that that be the process that we go through."

Her comments came as Kellyanne Conway, Mr Trump’s senior aide, told Fox News on Monday that "credible news sources" suggested there was politically motivated activity during the campaign.

She added that as president, Mr Trump "has information and intelligence that the rest of us do not."

On Sunday the New York Times reported that Mr Comey said that the FBI had never tapped the building, and had asked the department of justice to issue a statement denying the tapping. They are yet to do so.

On Monday morning it was reported that Mr Trump made his explosive allegation after Breitbart news – the controversial site formerly ran by his adviser Steve Bannon – reported a conspiracy theory discussed on a conservative radio station.

"The president firmly believes that the Obama administration may have tapped into the phones at Trump Tower and that this is something that we should look into," she said. "We'd like to know for sure."

She then turned to attack the media for its reporting of his administration.

"The media has been extremely dismissive of this reporting and this potential story while all the while being very happy to jump on all of the false attacks that have been launched at this president over the last six months," she said.

"All we're asking for is a fair and same look at this potential story and to let the House Intelligence Committee do their job."

"He's at a much higher classification than I am, so he may have access to documents that I don't know about," she said. "But I do know that we take this very seriously and we think it should be thoroughly reviewed and investigated and we're asking Congress to do their job."
